Henjo - Hen na Joshi Kousei Amaguri Chiko

maguri Senko is a high school girl with a cool personality (as in, kuudere) and a big pervert. She openly reads porn and masturbates, and isn't perturbed in the slightest at the sight of penises and such. The story is about two adult men that come to live and work for her father, who runs a company that does various oddjobs, which she helps out with. And the various forms of sexual harassment to which she subjects the one which she has taken a liking to.
